  Purpose

The purpose of this study is to learn if apixaban can prevent blood clots in the leg (deep vein thrombosis [DVT]) and lung (pulmonary embolism [PE]) that sometimes occur within patients hospitalized for acute medical illness, and to learn how apixaban compares to enoxaparin (Lovenox®) for preventing these clots. The safety of apixaban will also be studied.

Primary Outcome Measures:
  • Incidence of Composite of Adjudicated Total Venous Thromboembolism (VTE) and VTE-related Death During the Intended Treatment Period - Primary Efficacy Population [ Time Frame: Intended Treatment Period ] [ Designated as safety issue: No ]
    VTE: nonfatal pulmonary embolism (PE), symptomatic deep vein thrombosis (DVT), or asymptomatic proximal DVT detected by ultrasound. VTE-related death: fatal PE or sudden death for which VTE could not be excluded as a cause. Intended Treatment Period=period that started on day of randomization: period ended (for treated) at latter of a) 2 days after last dose of study drug and b) 32 days after first dose of study drug; period ended (for not treated) 32 days after randomization. A bilateral compression ultrasound (CUS) was performed between Days 5 and 14 for detection of asymptomatic proximal DVT unless a symptomatic VTE was confirmed prior. CUS was also performed on Day 30 ± 2 except for those participants who had a confirmed symptomatic VTE or proximal asymptomatic DVT prior to that time. All efficacy events were adjudicated by the Independent Central Adjudication Committee (ICAC). Event rate (%): n/N*100 (n=number with observation; N=total efficacy evaluable participants).

    Major bleeding was adjudicated by an ICAC using criteria from the International Society on Thrombosis and Hemostasis (ISTH) and was defined as acute clinically overt bleeding: associated with a fall in hemoglobin of 2 grams per deciliter (g/dL) or more, or leading to a transfusion of 2 or more units of packed red blood cells or 1000 milliliters (mL) or more of whole blood, or bleeding in a critical site or bleeding which is fatal. Incidence determined by Event Rate (%): n/N*100 (n=number with observation; N=total efficacy evaluable participants).

Treatment Period=includes measurements or events with onset from first dose of study drug through 2 days after the last dose of study drugs for bleeding endpoints. Incidence determined by Event Rate (%): n/N*100 (n=number with observation; N=total efficacy evaluable participants).

CRNM bleeding: acute clinically overt bleeding compromising hemodynamics; leading to hospitalization; traumatic subcutaneous hematoma; intramuscular hematoma; epistaxis that lasted for more than 5 minutes, was repetitive or led to an intervention; spontaneous gingival bleeding; spontaneous hematuria; macroscopic gastrointestinal hemorrhage; rectal blood loss.
